Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739828, here are decompositions:

5 + 8739823 = 8739828
7 + 8739821 = 8739828
17 + 8739811 = 8739828
59 + 8739769 = 8739828
61 + 8739767 = 8739828
79 + 8739749 = 8739828
89 + 8739739 = 8739828
107 + 8739721 = 8739828

Showing the first eight; more decompositions exist.
